Considered to be the most romantic color of metal, rose gold is stronger than both yellow and white gold because of the strength of the copper used. The more copper used, the redder the hue of the gold. Rose Gold Consisting of the entire red, blush, and pink gold shades, rose gold is formed by alloying pure gold with copper. However, the protective layer of Rhodium will gradually wear off and require re-plating. ![]() It is often plated with Rhodium, a white and reflective metal that provides an excellent protective coating. White Gold While not a true metal, white gold looks similar to platinum, and is made from yellow gold and various alloys, including nickel and zinc. The most historically popular of all three metal shades, yellow gold is easy to maintain for a lifetime of wear. As the amount of gold increases, so does the brightness of the yellow color. Yellow Gold The shade of yellow gold can vary based on the alloy. Some of the most common forms of gold alloy include:ġ8K Gold - 18 parts gold, 6 parts other metals by weight (75% pure)ġ4K Gold - 14 parts gold, 10 parts other metals by weight (58.3% pure)ġ0K Gold - 10 parts gold, 14 parts other metals by weight (41.7% pure) Consequently, it must be alloyed with other metals to give it strength. In its pure form, gold is soft and malleable, but scratches easily and is unsuited for jewelry wear. If gold is 100% pure, then it is 24 karat gold (24K). ![]() The higher the karat amount, the more pure the gold is. The purity of gold is measured in karats.
